I have switched to SRSRAN with DPDK and expected to get better/ more stable performance, However the opposite is happening, Is thee any special settings for DPDK with SRSRAN,
with out DPDK I have reached 1.4Gbps however with DPDK max is 700Mbps for one UE scenario.

That's UHD with DPDK. I think you have to go down the rabbit hole and benchmark UHD first with and w/o DPDK.

Also can you share a console trace/logs? Where do we lose the 700mbits?
